"The repeal of Proposition 8 in California is a significant milestone in the fight for marriage equality," Haggerty said. "The likelihood of the case now being argued before the U.S. Supreme Court will bring gay marriage into a full debate nationally, and eventually make equality a part of federal law. The historical imperative of same-sex equality seems to have finally reached a critical mass in society, making a once-reviled minority an integral part of the American community."

Haggerty was one of the historians on the study that resulted in "Don't Ask, Don't Tell," wrote an update to the policy in 2003, and continues to contribute articles to various publications about gays and lesbians in the military.
